Calculate the enthalpy change when 4.00 mol Cl2O7 is produced according to the following balanced equation:

Chemistry
1 answer:
marissa [1.9K]3 years ago
8 0

So the equation is,

2Cl2(g) + 7O2(g) + 130kcal -> 2Cl2O7(g)

from this , ΔH°rxn=130kcal.mol^{-1}

mol^{-1} is mentioned because it is for per mole of reaction. So for 4. moles of the product 2Cl_{2} O_{7} we need 4/2 moles of reaction to be used to calculate associated enthalphy change for the reaction.

Therefore4/2*130=260 kcal

How can erode soil affect the body of water. ASAP​
Murrr4er [49]
Soil erosion has consequences that go beyond the loss of fertile land. It has resulted in an increase in contamination and sedimentation in lakes and rivers, clogging them and causing fish and other animals to decline. Degraded lands are also less capable of retaining water, which can exacerbate flooding.

If during an experiment zinc was found to be more reactive than lead or copper, zinc would be considered the strongest _____.
densk [106]

Zinc would be considered the strongest reducing agent.

<h3>Reducing agent</h3>

A reducing agent is a chemical species that "donates" one electron to another chemical species in chemistry (called the oxidizing agent, oxidant, oxidizer, or electron acceptor). Earth metals, formic acid, oxalic acid, and sulfite compounds are a few examples of common reducing agents.

Reducers have excess electrons (i.e., they are already reduced) in their pre-reaction states, whereas oxidizers do not. Usually, a reducing agent is in one of the lowest oxidation states it can be in. The oxidation state of the oxidizer drops while the oxidizer's oxidation state, which measures the amount of electron loss, increases. The agent in a redox process whose oxidation state rises, which "loses/donates electrons," which "oxidizes," and which "reduces" is known as the reducer or reducing agent.

Element M has two isotopes,^104M and ^106M.
snow_lady [41]
To calculate atomic mass, you have to take to weighted average of the isotopes' masses. What that means is M = RA*106 + (1 – RA)*104, where RA is relative abundance expressed in decimal form. If you simplify the right side of that equation, you get M = 2*RA + 104. Doing a little more algebra yields RA = (M –104)/2 = (104.4 – 104)/2 = 0.4 / 2 = 0.2, which is 20%. So the answer is B.

What is the molarity of HCl if 34.81 mL of a solution of HCl contain 0.3297 g of HCl?
Temka [501]

Answer:

0.2598 M

Explanation:

Molarity is mol/L, so we have to convert the grams to moles and the mL to L. To convert between grams and moles you need the molar mass of the compound, which is 36.46g/mol.

0.3297gHCl*\frac{1molHCl}{36.46gHCL} = 0.00904279 mol HCl

34.81 mLHCl * \frac{1L}{1000L} = 0.03481 L HCl

\frac{0.00904279molHCl}{0.03481 L HCl} = 0.25977554 mol/L

Round to the lowest number of significant figures = 0.2598 M
