Which element below has properties of both metals and non metals ?
Answer:
I need more information.
Explanation:
Answer:
The answer is metalloids.
The metalloids are a unique group of elements that share properties of both metals and nonmetals. They're also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.
Hope this helps, have a great day/night, and stay safe!
The more electronegative atom in a covalent bond will: * 1 point become an anion become a cation have a partial positive charge have a partial negative charge
Answer:
The correct option is have a partial negative charge
Explanation:
Since electronegativity can be described as the measure of the tendency of atom to attract electrons towards itself, the more electronegative atom in a covalent bond will have a partial negative charge. This is because, in covalent bond, there is sharing of electrons between participating atoms, the atom that has a higher electronegativity tends to attract the shared electrons towards itself making it slightly negative charge.
NOTE: The negative charge is partial and thus is not represented while drawing a covalent bonding diagram as this could be misinterpreted to mean an electrovalent bond if the charge is indicated.
Based on what you know about the daughter cells that form by mitosis and meiosis, how do you think the offspring of asexually and sexually reproducing organisms compare to their parents? Justify your answer.
Answer:
well u see the offspring of asexual production will be identical to the parent because it only needs 1 parent where as sexual production requires 2 parents so it would look like both parents
The table below describes two parts of living cells.
WHO EVER ANSWERS IT I WILL GIVE BRAINIEST!!
Parts of Living Cells
Plant cell Animal cell
Part A Present Present
Part B Present Absent
Which of the following is most likely correct? (1 point)
a
Part A is vacuole, Part B is nucleus
b
Part A is mitochondria, Part B is cell wall
c
Part A is cell wall, Part B is cell membrane
d
Part A is chloroplast, Part B is mitochondria
Answer: membrane and cell wall
Explanation: this is because the cell wall is only known to happen in plant cells and a membrane is in both plant and animal cells so it is most likely membrane and cell wall.

Brian's family has a compost pile at home. They put all the weeds they pull up from the garden in it as well as any vegetable waste they gather from the kitchen. If they keep it moist, all this vegetation will
eventually turn into organic soil by the chemical process of decay. Since decay involves a variety of chemical reactions, how might temperature affect the rate at which the compost turns into sol?
Temperatures near freezing would make it speed up.
It would happen faster at warmer air temperatures.
Changing temperatures would not affect the chemical reactions.
Warm summer air temperatures would make it slow down.
Answer:
Option - It would happen faster at warmer air temperatures
Explanation:
The chemical process of converting organic matter such as plants, litter into organic soil, or organic compost called decomposition and perform by decomposers such as fungus or bacteria.
Like all other living organisms, decomposers also live in an optimal range of temperature. The major decomposers normally lie in the range of 30 to 40-degree celsius. Any type of fluctuation in this range might slow down the reaction of decomposition.
In all organisms, energy is stored in molecules called:
A. mitochondria
B. heat
C. glucose
D. ATP

Answer:
Explanation:
1 billion carbon atoms = 10⁹ carbon atoms .
33% were burnt
67 % remained behind .
67 % of 10⁹ = 6.7 x 10⁸
6.02 x 10²³ atoms = 1 moles
6.7 x 10⁸ atoms = 6.7 x 10⁸ / 6.02 x 10²³
= 1.11 x 10⁻¹⁵ moles

A sample of xenon gas occupies 1.90L at 251 kPa and -18°C. What was the temperature of the xenon if the gas originally measured 1.65 L at 205 kPa?
The temperature of the xenon : 180.863 K
Further explanationCombined with Boyle's law and Gay Lussac's law
[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]
P1 = initial gas pressure (N/m² or Pa)
V1 = initial gas volume (m³)
P2 = final gas pressure
V2 = finalgas volume
T1 = initial gas temperature (K)
T2 = final gas temperature
P1=251 kPa
T1=-18+273=255 K
V1=1.9 L
P2=205 kPa
V2=1.65 L
[tex]\tt \dfrac{251\times 1.9}{255}=\dfrac{205\times 1.65}{T_2}\\\\T_2=\dfrac{205\times 1.65\times 255}{251\times 1.9}=180.863~K[/tex]
When ice cubes cause weathering, what type of weathering is it called?
Answer:
Chemical Weathering
Explanation:
Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals. These minerals are stable at the Earth's surface. Water, carbon dioxide, and oxygen are important agents of chemical weathering.

If an object has a density higher than water, it will sink, and the piece of wood is more dense than water when measured.
What Happens When extra Solute is added to unsaturated ,saturated and supersaturated solution
Answer:
If More solute is added and it does not dissolve,then the original solution was saturated. if the added solute dissolves,then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturated.

What can cause the pH of water to be either to basic or to acidic
But pH is quite an important measurement of water. Maybe for a science project in school you took the pH of water samples in a chemistry class ... and here at the U.S. Geological Survey we take a pH measurement whenever water is studied. Not only does the pH of a stream affect organisms living in the water, a changing pH in a stream can be an indicator of increasing pollution or some other environmental factor
