Answer:
I think it's c
Explanation:
if they were different temperatures then there would be conduction because other thermal energy will conduct to the lower temperature to reach a equal librium
Answer:
10.4 moles
Explanation:
Given parameters:
Number of moles of oxygen = 5.2moles
Number of moles of nitrogen monoxide = ?
Solution:
To solve this problem, we need to work from the known to the unknown specie according to the reaction.
Oxygen gas is known and we can estimate the amount of mole of nitrogen monoxide;
Let us write the balanced reaction equation;
N₂ + O₂ → 2NO
according to this reaction;
1 mole of oxygen gas will produce 2 mole of NO
5.2 moles of oxygen gas will produce (5.2 x 2)moles = 10.4moles
D -a substance made of more than one type of atom
Option a) H-H is the correct answer
Answer:
1.03 M
Explanation:
Step 1: Write the balanced equation
NaOH + HCl ⇒ NaCl + H₂O
Step 2: Calculate the reacting moles of HCl
30.0 mL (0.0300 L) of 0.500 M HCl react.
0.0300 L × 0.500 mol/L = 0.0150 mol
Step 3: Calculate the moles of NaOH that react with 0.0150 moles of HCl
The molar ratio of NaOH to HCl is 1:1. The moles of NaOH that react are 1/1 × 0.0150 mol = 0.0150 mol.
Step 4: Calculate the molar concentration of NaOH
0.0150 moles of NaOH are in 14.5 mL (0.0145 L).
M = 0.0150 mol/0.0145 L = 1.03 M
