It's a chemical change beacause elements are combining to make something new! :)

Ok......
Nitroglycerin is a Compound. If you explode nitroglycerin would produce C02 and H20. That would be a looottt of energy so it would be a chemical change.

Using complete sentences, explain how to predict the products and balance the reaction between sulfuric acid and potassium hydro
Dahasolnce [82]

The product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.

<h3>What is the reaction between sulfuric acid and potassium hydroxide?</h3>

The result will be, H+ from H₂SO₄ reacts with OH- from KOH to generate H₂O. Also, K+ reacts with SO₄²⁻ to create K₂SO4₄

As a result, the balanced equation will be:

\rm H_2SO_4 + 2KOH --- > K_2SO_4 + 2H_2O

Thus, the product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. Sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.

Why do scientists use the scientific method?
xeze [42]

Answer:

Scientists use the scientific method because it is evidence-based, standardized and objective in conducting experiments. The scientific method allows scientists to stick to facts and to avoid the influence of preconceived notions and personal biases in research processes, improving the credibility of research findings.

g The gas phase decomposition of sulfuryl chloride at 600 K SO2Cl2(g) SO2(g) + Cl2(g) is first order in SO2Cl2 with a rate const
Alex_Xolod [135]

Answer : The concentration of SO₂Cl₂ after 720 min will be, 3.81\times 10^{-4}M

Explanation :

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  = 2.80\times 10^{-3}\text{ min}^{-1}

t = time passed by the sample  = 720 min

a = initial amount of the reactant  = 2.86\times 10^{-3}M

a - x = amount left after decay process = ?

Now put all the given values in above equation, we get

720=\frac{2.303}{2.80\times 10^{-3}}\log\frac{2.86\times 10^{-3}}{a-x}

a-x=3.81\times 10^{-4}M

Therefore, the concentration of SO₂Cl₂ after 720 min will be, 3.81\times 10^{-4}M

Calculate the amount of heat in kilojoules required when 13.0 g of water at 52.5°C is converted to
Sedbober [7]

Answer:

Q = 10.10059 KJ

Explanation:

Given data:

Amount of water = 13.0 g

Initial temperature = 52.5°C

Final temperature = 238.2°C

Heat required to convert it into steam = ?

Solution:

Specific heat capacity of water is 4.184 J/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 238.2°C - 52.5°C

ΔT = 185.7 °C

by putting values,

Q = 13.0 g × 4.184 J/g.°C × 185.7 °C

Q = 10100.59 J

Jolue to Kj:

10100.59j × 1 KJ/1000 J

Q = 10.10059 KJ
