What role does the reactivity of the reactants play in determining the rate of a chemical reaction?

Metals give up electrons to become cation or anion

galina1969 [7]

Metals usually become cations since electrons are negatively charged and when they are lost there are more protons than electrons making a positive net charge in the atom. (cations are positively charged ions while anions are negatively charged ions)

I hope this helps. Let me know if anything is unclear.

What pressure is required to achieve a co2 concentration of 7.90×10−2 m at 20∘c?

Savatey [412]

Answer:- 1.90 atm

Solution:- It is based on combined gas law equation, PV = nRT

In this equation, P is pressure, V is volume, n is moles of gas, R is universal gas constant and T is kelvin temperature.

If we divide both sides by V then:

$P=\frac{nRT}{V}$

We know that, molarity is moles per liter. So, in the above equation we could replace $\frac{n}{V}$ by molarity, M of the gas. The equation becomes:

P = MRT

T = 20 + 273 = 293 K

M = $7.9*10^-^2$

Let's plug in the values in the equation:

P = $(7.9*10^-^2)(0.0821)(293)$

P = 1.90 atm

So, the pressure of the gas is 1.90 atm.

Some compounds are better known by their common names than by their systematic chemical names. Give the chemical formulas of the

kondaur [170]

Explanation:

(a) Dry ice is solid carbon dioxide and its chemical formula is solid $CO_{2}$ .

(b) Sodium chloride is commonly known as salt in daily life. Hence, chemical formula of salt is NaCl.

(c) Laughing gas is also known as dinitrogen monoxide. Hence, its chemical formula is $N_{2}O$ .

(d) Marble (chalk limestone) is chemically known as calcium carbonate. Hence, its chemical formula is $CaCO_{3}$ .

(e) Baking soda is chemically known as sodium bicarbonate. Hence, its chemical formula is $NaHCO_{3}$ .

(f) Ammonia has a chemical formula as $NH_{3}$ .

(g) Water has a chemical formula as $H_{2}O$ .

(h) Milk of magnesia is a base and it is chemically known as magnesium hydroxide. Its chemical formula is $Mg(OH)_{2}$ .

(i) Epsom salt is most often found as heptahydrate of sulfate mineral epsomite. Its chemical formula is usually $MgSO_{4}.7H_{2}O$ . If not present as a heptahydrate then its chemical formula is $MgSO_{4}.(H_{2}O)_{x}$ where, value of x can be equal to 0 to 7.
