It has ns1 electron configuration like the alkali metals.
Answer:
Ok, is this a true and false question? Anyways, yes. the central dogma, from dna transcription to mRNA translation to proteins. and further regulation can occur through post-translational modifications of proteins. it is a true statement
Explanation:
C = 12.818 mg CO2 (1 mmol CO2/44 mg CO2) (1 mmol C/1 mmol
CO2) = 0.29 mmol
H = 3.675 mg of H2O (1 mmol H2O/18 mg H2O) (2 mmol H/1
mmol H2O) = 0.41 mmol
N = (4.725 mg – 0.29 * 12 – 0.41 * 1) * (1 mmol/14 mg) =
0.06 mmol
Divide everything by the smallest number:
C = 0.29/0.06 = 4.8 ~ 5
<span>H = 0.41/0.06 = 6.8 ~
7</span>
N = 0.06/0.06 = 1
Empirical formula is:

A. 0.12 (mol/L)/s
rate = 1 x 10-2 • 2^2 • 3
Answer:
64.0
Explanation:
2Mg+O2 ---> 2MgO
use dimentional analysis to find the amount of moles of O2 needed first
4.00molMg x 1.00mol O2/ 2.00 mol Mg=. 2.00 mol O2
using the coefficients you can see the mole ratio for O2:Mg the mole ratio is 1:2 which is why there is 1 mole on the top for 2 moles on the bottom. The Mg would cancel and multiply 4 by 1 then divide by 2, or multipy 4 by 1/2
Now that you have the moles of O2 you use the molar mass to find the grams in 2 moles of O2
2.00 mol O2 x 32.0g/1.00 mol = 64.0 g
multiply 2 by 32
