Answer:

Check the explanation

Explanation:

In the field of organic chemistry, keto–enol tautomerism refers to equilibrium of chemical substance that is among a keto form (an aldehyde or a ketone) and an enol (an alcohol). The enol and the keto forms are believed to be tautomers of each other. The keto form preponderate at equilibrium for a large amount of ketones.

When the solar system was very young, the sun was just being formed and planets had not yet been made. The solar system was most
andriy [413]

Answer:

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. ... When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. At the center, gravity pulled more and more material in.

Explanation:

When the solar system was very young, the sun was just being formed and planets had not yet been made. The solar system was mostly gas and dust.

in conclution its d

Planets formed from small amounts of debris that were attracted together because of gravity.

Water is placed in a graduated cylinder and the volume is recorded as 43.5 ml. a homogeneous sample of metal pellets with a mass
natulia [17]
Density = mass /volume of the body. mass = 10.88 g, volume of the liquid displaced= 49.4-43.5=5.9 ml.

density = 10.88/5.9=1.844 g/ml~1.84 g/ml

The volume displaced is exactly the same as that of the body (The Eureka fro Archimedes!)

What is the volume occupied by 3.00 mol of hydrogen gas at STP? *
xxTIMURxx [149]

Answer: V=67.2 L

Explanation:

For this problem we will need to use the Ideal Gas Law.

Ideal Gas Law: PV=nRT

P=1.00 atm (STP)

V=?

n=3.00 mol

R=0.08206Latm/Kmol

T=273.15 K (STP)

To find V, we would manipulate the equation to V=nRT/P

V=\frac{(3.00 mol)(0.08206Latm/Kmol)(273.15K)}{1.00 atm}

V=67.244 L

With significan figures, our answer is V=67.2 L.

What volume of 0.4567 m h2so4 is required to neutralize 30.00 ml of 0.3210 m naoh?
sertanlavr [38]
Answer is: volume of H₂SO₄ is 42.1 mL.<span>
Chemical reaction: H</span>₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O.<span>
c(H</span>₂SO₄) = 0,4567 M = 0,4567 mol/L.<span>
V(NaOH) = 30 mL </span>÷ 1000 mL/L <span>= 0,03 L.
c(NaOH) = 0,321 M = 0,321 mol/L.
n(NaOH) = c(NaOH) · V(NaOH).
n(NaOH) = 0,321 mol/L · 0,030 L.
n(NaOH) = 0,00963 mol.
From chemical reaction: n(H</span>₂SO₄) : n(NaOH) = 1 : 2.<span>
n(H</span>₂SO₄) = 0,01926 mol.<span>
V(H</span>₂SO₄) = n(H₂SO₄) ÷ c(H₂SO₄).<span>
V(H</span>₂SO₄) = 0,01926 mol ÷ 0,4567 mol/L.<span>
V(H</span>₂SO₄<span>) = 0,0421 L = 42,1 mL.</span>
