8 0

A. 1:3

The equation shows that 1 mol Fe_3_O4 ≡ 3 mol Fe.

∴ The mole ratio is Fe_3_O4:Fe = 1:3.

“B. 1:4” is <em>incorrect</em>. It is the mole ratio of <em>Fe_3O_4:H_2O </em>and of<em> Fe_3O_4:H_2</em>.

“C: 3:1” is <em>incorrect</em>. It is the mole ratio of <em>Fe:Fe_3O_4</em>.

“D: 4:3” is <em>incorrect</em>. It is the mole ratio of <em>H_2O:Fe and of H_2:Fe</em>.

coldgirl [10]

The balanced chemical equation representing the process of photosynthesis is:

6 CO_{2} +12H_{2}O-->C_{6}H_{12}O_{6}+6O_{2}

The reactants in the process of photosynthesis are CO_{2}and HH_{2}O and the products of the reaction are glucose C_{6}H_{12}O_{6} and oxygen O_{2}. Oxygen is the nonpolar covalent gas which is released in the process of photosynthesis. The reactant CO_{2} is a nonpolar covalent gas while the other reactant waterH_{2}O has polar covalent O-H bonds.

In the balanced chemical equation, the number of each type of element must be equal on both sides of the reaction.

Name this compound please​
koban [17]

Answer:

The answer to your question is butanal

Explanation:

To name this compound we must consider:

1.- Identify the functional group. The functional group of this molecule is the first carbon to the right and its oxygen.

When carbon is attached to oxygen is a border, this functional group is called Aldehyde.

2.- Count the total number of carbons starting from the right. This molecule has 4 carbons.

3.- Name the compound

    An organic molecule with 4 carbons is called butane but change the ending for al, then the name will be butanal

What happens to the ions when the drain is turned off? please help :] ❤️
kkurt [141]

Answer:

In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates.
