Change in temperature affects the rate of reaction since it causes a change in the number of collisions per unit time. These collisions cause the breaking of bonds and formation of new ones giving out new products. An increase in temperature increases the rate of collisions hence increasing the rate of reaction while a decrease in temperature leads to a decrease in the rate of reaction due to the decreased number of collisions per unit time. thus the correct choice for blank A is: B. the number of collisions between molecules and for blank B: decrease.
Answer:
1) 37100000
2) 330000000
Explanation:
1) 3.7 x 10^7 = 37100000
2) 3.30 x 10^8 = 330000000
(Hope this helps can I pls have brainlist (crown)☺️)
Answer:
2M
Explanation:
Molarity refers to the molar concentration of a solution. It can be calculated by using the formula as follows:
Molarity (M) = number of moles (n) ÷ volume (V)
Based on the information provided in this question, 2 moles of salt is dissolved to form 1 liter of solution. This means that n = 2mol, V = 1L
Molarity = n/V
Molarity = 2/1
Molarity = 2M
6CO2 + 6H2O → C6H12O6 + 6O2
glucose produced = 1/6 x 23.6 = 3.93 moles
Answer:
Explanation:
2C7H6O2 + 15O2 → 14CO2 + 6H2O.
