Answer:

The word gentle traces back to the Latin word gentlis, meaning “of the same clan,” and at first the world was used to describe people belonging to distinguished families, who were seen as courteous and noble. Nowadays you’re more likely to hear the word used to refer to things that are calm, moderate, and without harshness. The word is often applied to people, but it can be used more broadly to describe anything that is mild, such as "a gentle detergent" or "a gentle reminder."

Answer:

Average amu is 6.52556

Explanation:

Average the numbers

Add the two masses together.

6.01512+ 7.01600= 13.03112

Then divide by 2, we divide by 2 because that is how many #'s we are given.

13.03112/ 2= 6.52556

Orange juice is mixture.

Answer:

[tex]\boxed {\boxed {\sf Mixture}}[/tex]

Explanation:

An element is pure and all the atoms have the same atomic number. An element has a symbol and can be found on Periodic Table of Elements.

A mixture is created when two or more substances are combined physically.

Orange juice can't be found on the Periodic Table of Elements. Orange juice is made up of many different substances/ingredients, like water, sugar, and juice from the orange.

Therefore, orange juice is considered to be a mixture. More specifically, a homogenous mixture because it is uniform. (*applies to pulp-free orange juice). If it has pulp, it would be a heterogenous mixture.

Answer:

potential energy (im positive that its right)

Answer:

This approximation of mass can be used to easily calculate how many neutrons an element has by simply subtracting the number of protons from the mass number. Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers.

Answer:

mass number

The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers, than finally after death of an organism, to decomposers

The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

The sequence of events within an ecosystem known as a "food chain" occurs when one live organism eats a different organism, which is then eaten by a larger organism. A food chain is created by the transfer of energy as well as nutrients from one creature to another at various trophic levels. A food web is comprised of numerous linked food chains.

The feeding habits or connections between living things are also explained by the food chain. Trophic level is the term used to describe the orderly phases in a food chain, from producers from the bottom through primary, secondary, and tertiary consumers. A trophic level is any position along a food chain.  A food web and a food chain are similar, but a food web seems far bigger. The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

Therefore, the direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

Answer: it moves faster

Explanation:

When heat is added it gains thermal energy therefore it moves faster as things heat up and it loses thermal energy when it gets cooler causing particles to move slower

Answer: Option C.

The evaporation of water out of the stomata of plants

Explanation:

The evaporation of water out of the stomata of plants is transpiration because transpiration is the evaporation or loss of water inform of vapor from the stomata of leaves or flowers. Water is first absorbed by the root and it is moved to plant parts including leaves by xylem vessels since the roots already retained which it can use and when the water get to the leaves, it is loss inform of water vapor.

Answer:

6C(s) + 6H2(g) + 3O2(g) --------------------> C6H12O6(s).

Explanation:

One of the examples under the type of sugar; monosaccharide(simple sugar) is the glucose. Glucose(with IUPAC name as D-glucose) as a monosaccharide (simple sugar) has the molar mass of 180.156 g/mol and a Melting point of 146 °C.

Thus, the unbalanced chemical reaction for the formation of glucose is given below;

C(s) + H2(g) + O2(g) --------------------------> C6H12O6(s) ΔH°f = -1273.1KJ/mol.

The balanced chemical reaction for the formation of one mole of glucose is given as;

6C(s) + 6H2(g) + 3O2(g) --------------------> C6H12O6(s).

The balanced chemical equation for the standard formation reaction of solid glucose is: [tex]\mathbf{6C_{(s)} + 6H_{2(g)} +3O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ }[/tex]

Glucose is a simple sugar of a class of carbohydrates known as monosaccharides. It is the principal metabolite for energy production in the human body.

The formation of solid glucose [tex]\mathbf{C_6 H_{12} O_6_{(s)}}[/tex] occurs by the reaction of carbon, hydrogen, and oxygen.

The reaction formation of the solid glucose is:

[tex]\mathbf{C_{(s)} + H_{2(g)} +O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ \Delta H_f^0= -1273.1 \ kJ/mol}[/tex]

Now, the balanced chemical equation can be expressed as follows;

[tex]\mathbf{6C_{(s)} + 6H_{2(g)} +3O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ }[/tex]

Explanation: When you chill a substance when it is mixed with another substance, ( chilled vinegar mixed with sodium bicarbonate will react slower for instance) it reacts slower do to the molecules slowing down when chilled.

[tex]\huge\boxed{Option D}[/tex]

a liquid mixture in which the the solute which is in a smaller proportion is uniformly distributed within the the solvent which is the major component is called a solution.

It increases the rate of reaction,  because when we stir the solute in the solution, the mixed solute particles are distributed more further than when they are left stationary, making the environment (which surrounds the solute) less concentrated by the dissolved solute thus the rate increases and more solute is mixed.

No, A reacting substances  in water are those which can react with water that are Ionic metal. Water is made of ions [tex]H^+ and OH^-[/tex]. Substances(solute), they mix or dissolve more because Solutes ions interact with the ions of a water(solvent), thus breaking the bonds between the solute and then ions of solute form bond with the ions of water. Thus the rate increases in water.

No, because by the increase in temperature, the kinetic energy of more  molecules of a substance increase which results in reaching the threshold energy(minimum energy required by the molecules to change into product) of more molecules. So less molecules are left with low energy.

Yes, the rate of reaction decreases because  the molecules are slower and collide less. Less molecules make the effective collisions due to which the kinetic energy of molecules is less, so less molecules make up to the threshold energy. So decrease in temperature lowers the rate of the reaction.

Answer: In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products. If we count the number of hydrogen atoms in the reactants and products, we find two hydrogen atoms.

Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).
