Answer:535.5g

Explanation:

1) find the volume of the object

=L*W*H

=1.8*3.5*10.0

=63cm^3

2) the original formula is solving for the dencity which we have so...

D=M/V

M=D*V

M=8.5(63)

M=535.5g

Determine how many subatomic particles are in the following days

ololo11 [35]

Answer:

Number of protons in Na²⁴ = 11

Number of neutrons in Na²⁴ = 13

Number of electrons in Na²⁴ = 11

Number of protons in I¹³¹ = 53

Number of neutrons in I¹³¹ = 78

Number of electrons in I¹³¹ = 53

Explanation:

Sodium is present in group one.

Atomic number of sodium is 11.

Its atomic mass is 23 amu.

Electronic configuration:

Na₁₁ = 1s² 2s² 2p⁶ 3s¹

Number of protons in Na²⁴ = 11

Number of neutrons in Na²⁴ = 13 (24-11= 13)

Number of electrons in Na²⁴ = 11

Iodine:

Iodine is halogen element.

Its atomic number is 53.

Its atomic mass is 127 amu.

Electronic configuration:

I₅₃= [Kr] 4d¹⁰ 5s² 5p⁵

Number of protons in I¹³¹ = 53

Number of neutrons in I¹³¹ = 78 (131-53= 78)

Number of electrons in I¹³¹ = 53

What effect does fermented sugar have in beer brewing

LiRa [457]

Answer:

If the sugar concentration level of the must becomes too high at any given point--either at the beginning or during the fermentation--it starts to have an inhibiting effect on the yeast's ability to produce alcohol. In other words, the higher sugar concentration starts to act as a preservative effecting the fermentation in a negative way.

Explanation:

Fermentation is the process by which yeast converts the glucose in the wort to ethyl alcohol and carbon dioxide gas -- giving the beer both its alcohol content and its carbonation.

After 11.5 days, 12.5% of a sample of radon-222 that originally weighed 42g remains. What is the half-life of this isotope?

Bond [772]

Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value. The equation to describe the decay is
Nt=N0(1/2) $^{t/t(1/2)}$ where N0 is the initial quantity, Nt is the remaining quantity after time t, t1/2 is the half-time. So work out the equation, t1/2 = t (-ln2)/ln(Nt/N0) = 11.5*(-ln2)/ln(12.5/100) = 3.83 days
