Answer:

The vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.

Explanation:

The products in the equation would be  [tex]CO_2[/tex], [tex]SO_2[/tex], and [tex]H_2O[/tex].

From the equation of the reaction:

[tex]CH_3SH + 4O_2 --- > CO_2 + SO_2 +2H_2O[/tex]

The products are [tex]CO_2[/tex], [tex]SO_2[/tex], and [tex]H_2O[/tex].

This is because, for every chemical equation, the reactants are always at the back of arrows while products are at the front of arrows. In other words, reactants are usually on the left-hand side while products are on the right-hand side.

Terbium-147 undergoes positron emission to become a stable atom, the stable atom is ₆₄Gd¹⁴⁷.

Series (or family) of natural radioactive decay is the set of elements with unstable nuclei, which follow an orderly sequence of spontaneous decay, that is, they emit alpha and beta particles, until a stable lead nucleus is created.

In this case, natural radioactive decay occurs when the nucleus of the atom of some chemical element is unstable and then it "breaks", releasing electromagnetic radiation and disintegrating.

Answer:

a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.

Weak bases are alkaline solution that does not get completely dissociated. The dissociation constant will be the ratio of the concentration of the products to the reactants.

The weak base ionization constant is the equilibrium constant that is given as the division of the products of the ionization to the concentration of the reactants.

The reaction for HCO₃ is given as:

HCO₃⁻ + OH⁻ ⇄ CO₃²⁻ + H₂O

The value of Ka for the given reaction will be:

Ka = [CO₃²⁻][H₂O] ÷ [HCO₃⁻ ][OH⁻]

Therefore, the Ka of the weak carbonic acid is given as the ratio of the concentration of the products to the reactants.

Answer:

400°C

Explanation:

22,000 cal / (0.11 cal/g°C x 500 g) = 400°C

Answer:

400 C degree change

Explanation:

22 000 cal = 500 g * (C) * .11 cal / g-C

C = 22 000 / (500*.11)   = 400 C  degree change

42.6897 grams of carbon dioxide would be produced from the following reaction, if 175 kJ of energy is given off.

The mole (symbol mol) is the SI base unit of material quantity. The amount of substance in an object or sample is a measure of how many elementary entities of a certain substance are present.

Given chemical reaction is:

[tex]2CO + O_2[/tex]  → [tex]2 CO_2[/tex]

From the stoichiometry of the reaction, it is clear that 2 moles of carbon dioxide are produced.

Actual moles will be calculated by using the enthalpy and energy value as:

Actual moles of [tex]CO_2[/tex] = 275kJ × ([tex]\frac{2 mol}{566 kJ}[/tex]) = 0.97 moles.

Grams of carbon dioxide = moles  X molar mass of carbon dioxide.

Grams of carbon dioxide = 0.97  X 44.01 g/mol

Grams of carbon dioxide = 42.6897 g

This question involves the concepts of time period and tangential speed.

The tangential speed of the object is "5.1 x 10⁴ m/s".

The following formula gives the time period of the object:

[tex]T=\frac{2\pi}{\omega}\\\\[/tex]

[tex]\omega = \frac{2\pi}{T}[/tex]

where,

Therefore,

[tex]\omega=\frac{2\pi}{2.2\ x\ 10^4\ s}\\\\\omega=2.86\ x\ 10^{-4}\ rad/s[/tex]

Now, the tangential speed can be given by the following formula:

[tex]v=r\omega[/tex]

where,

Therefore,

[tex]v=(1.8\ x\ 10^8\ m)(2.86\ x\ 10^{-4}\ rad/s)[/tex]

v = 5.1 x 10⁴ m/s
