Answer:
1.668 S
Step-by-step explanation:
We are given that
Product
For first order reaction,
Rate constant=k=
Temperature=
We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.
Substitute the values then we get
Hence, it would take 1.668 s for the concentration of A to decrease from 0.790 M to 0.230 M.
<span>The correct
answer is 3.24 grams per cubic centimetre. As a matter of fact, the
lunar soil’s mean density may range from 2.90 to 3.24 g cm-3 which highly
depends on the type of ingredients present in its resource materials.</span>
X=1 and y=4. first I did
3x+2y=11
y=5x-1
and 3x+2(5x-1)=11
=3x+10x-2=11
=13x-2=11
cancel 2 out
13x=13
x=1. then simply add x in the original y equation,
y=5x-1
y=5(1)-1
y=5-1
y=4.
check your work
3(1)+2(4)=11
4=5(1)-1
again X=1 AND Y=4
Hope this helped

Answer:
C) Distributive Property
Step-by-step explanation:
You're <em>distributing</em> in the 3 when you multiply it by the 5 and the 2 in the algebraic process:
➦ ➦
3•(5 + 2) = (3 • 5) + (3 • 2)
So, the 3 was <em>distributed</em> between the 5 and 2 when you multiplied.
Hence, this is the distributive property.
