A net ionic equation which tends to show the ions that underwent a change in the reaction

<h3>What is a reaction equation?</h3>

The term reaction equation is the term that can be used to describe the instance where reactants combine together. If this occurs in solution we can say that the reaction is an aqueous phase reaction because the reactants wee all dissolved in solution.

It is possible for ionic substances in solution to react. When this occurs, it is possible for us to put down a net ionic equation which tends to show the ions that underwent a change in the reaction and the product of this reaction may be a liquid, a gas or a solid.

In this case, the complete molecular equation can be written as;

Ba(NO3)2(aq) + Na2SO4(aq) -----> BaSO4(s) + 2NaNO3(aq)

The complete ionic equation can be written as;

Ba^2+(aq) + 2NO3^-(aq) + 2Na^+(aq) + SO4^2-aq) -----> BaSO4(s) + 2NO3^-(aq) + 2Na^+(aq)

Net ionic equation is;

Ba^2+(aq) + + SO4^2-aq) -----> BaSO4(s)

For a reaction that follows the general rate law, Rate = k[A][B]2, what will happen to the rate of reaction if the concentration

sleet_krkn [62]

Answer:

The rate will increase by a factor of 5.00 too.

Explanation:

Hello,

In this case, given the rate law:

$r=k[A][B]^2$

Thus, we can notice it is first-order respect to A, for that reason, increasing its concentration by a factor of 5.00, increase the rate by a factor of 5.00 as well.

Moreover, if the concentration of B is increased by the same factor, the rate will increase by a factor of 25.00, since the rate is second-order respect to B (it is squared).

Best regards.

the half life of I -137 is 8.07 days. if 24 grams are left after 40.35 days, how many grams were in the original sample?

Ray Of Light [21]

Answer:

768g

Explanation:

We can use to formula $N(A) = N_0(\frac{1}{2})^\frac{t}{t_{1/2}}$ . Here, N(A) is the final amount. N0 is the initial amount. t is the time elapsed, and $t_{1/2}$ is the half life. Plugging in, we get the answer above.

Scientists define work as the spending of energy.<br><br> True<br> False

Hoochie [10]

True; scientist define work as the spending of energy. This is because energy is required to move an object. For work to be done an object has to be moved from one point to another. Work is measured in joules similar to energy which is also measured in joules. Mathematically, work done is given by the product of force and distance moved by an object or a body.

Nicotine, a component of tobacco, is composed of c, h, and n. a 4.725 −mg sample of nicotine was combusted, producing 12.818 mg

ehidna [41]

C = 12.818 mg CO2 (1 mmol CO2/44 mg CO2) (1 mmol C/1 mmol CO2) = 0.29 mmol

H = 3.675 mg of H2O (1 mmol H2O/18 mg H2O) (2 mmol H/1 mmol H2O) = 0.41 mmol

N = (4.725 mg – 0.29 * 12 – 0.41 * 1) * (1 mmol/14 mg) = 0.06 mmol

Divide everything by the smallest number:

C = 0.29/0.06 = 4.8 ~ 5

N = 0.06/0.06 = 1

Empirical formula is:
