Atoms are the smallest building block that can affect things, and are many many times smaller then cells. our eyes are not designed to see such small things

The reason they are small because they are made out of smaller partials. Also it's normal for us to not see them because of how small they are.<span />

(I will give brainliest, ONLY if its correct!)

ryzh [129]

Answer:

easy

Explanation:

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

Relative formula mass of glucose? (C6H12O6)

Rom4ik [11]

To find the mass of glucose, you must multiply the atomic weight of each of the elements in the molecule by the subscripts in the formula:

$C_{6}=6*(12.01g)=72.06g$

$H_{12}=12*(1.008g)=12.096g$

$O_{6}=6*(15.999g)=95.994g$

Then you add all of them together:

$72.06g+12.096g+95.994g=180.15g$

Therefore, the molar weight of glucose is 180.15 grams.

Explanation:

(NH₄)⁺(SO₄)²⁻+H₂O⇒(NH₄)⁺O²⁻+H₂(SO₄)²⁻

(NH₄)₂(SO₄)+H₂O⇒(NH₄)₂O+H₂(SO₄)

For the following reaction, 0.511 moles of sulfuric acid are mixed with 0.464 moles of zinc hydroxide. What is the formula for t

kkurt [141]

Answer:

Zinc hydroxide, Zn(OH)₂ is the limiting reactant.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

H₂SO₄ + Zn(OH)₂ —> ZnSO₄ + 2H₂O

From the balanced equation above,

1 mole of H₂SO₄ reacted with 1 mole of Zn(OH)₂.

Finally, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

1 mole of H₂SO₄ reacted with 1 mole of Zn(OH)₂.

Therefore, 0.511 mole of H₂SO₄ will also react with 0.511 mole of Zn(OH)₂.

From the calculation made above, we can see that it will take a higher amount (i.e 0.511 mole) of Zn(OH)₂ than what was given (i.e 0.464 mole) to react completely with 0.511 mole of H₂SO₄.

Therefore, Zn(OH)₂ is the limiting reactant and H₂SO₄ is the excess reactant.
