Answer:
24m/s
Explanation:
a=change of v/change of t
6m/s^2=v/4s
multiply both sides by 4s
v=24m/s
Tomato juice or acid rain
Answer: -
sigma factor mRNA RpoH sigma H sigma 32
Explanation: -
It is the heat shock sigma factor which activates due to heat. The factor will bind with to the polymerase-core-enzyme. After this other heat ans shock proteins are expressed.
This thus enable the cell to survive higher temperatures. Some of the enzymes that are expressed upon activation are chaperones, proteases and DNA-repair enzymes
Answer:
Molar mass of H3PO4 = 97.99 g/mol (Approx.)
Explanation:
Find:
Molar mass of H3PO4
Given;
Molar mass of H = 1.0079 g/mol
Molar mass of P = 30.974 g/mol
Molar mass of O = 15.999 g/mol
Computation:
Molar mass of H3PO4 = (1.0079)(3) + 30.974 + 15.999(4)
Molar mass of H3PO4 = 3.0237 + 30.974 + 63.996
Molar mass of H3PO4 = 97.9937
Molar mass of H3PO4 = 97.99 g/mol (Approx.)
Data:
Molarity, M = 1.25 M
mass, m = 36 grams
Solute, H2SO4
Formulas:
M = n / V => V = n / M
n = mass in grams / molar mass
Solution:
molar mass of H2SO4 = 98.079 g/mol
n = 38 g / 98,079 g/mol = 0.3874 mol
V = 0.3874 mol / 1.25M = 0.31 liter
Answer: 0.31 liter
