How many moles of H2O are needed to react with a mole of 3.0 of Na?​

Chemistry
1 answer:
AveGali [126]2 years ago
5 0

Answer: 3.0 moles of water (H_2O)  are needed to react with a mole of 3.0 of Na

Explanation:

The balanced chemical reaction of sodium with water is as follows:

2Na+2H_2O\rightarrow 2NaOH+H_2

According to stoichiometry:

2 moles of sodium (Na) reacts with = 2 moles of water (H_2O)

Thus 3.0 moles of sodium (Na) reacts with = \frac{2}{2}\times 3.0=3.0 moles of water (H_2O)

3.0 moles of water (H_2O)  are needed to react with a mole of 3.0 of Na

Water sits in an open beaker. assuming constant temperature and pressure, the vapor pressure of the water ______________ as the
user100 [1]

For a given system, vapor pressure can be defined as the pressure exerted by the vapor phase in equilibrium with the condensed phase.

In this case, as water sits in an open beaker it tends to evaporate thereby forming water vapor. This vapor phase then exerts a pressure over the liquid water, which is termed as the vapor pressure of water at that temperature and pressure. As water continues to evaporate, more and more molecules escape into the vapor phase which thereby increases the vapor pressure.

Ans: The vapor pressure of water increases as the water evaporates.

How many atoms does one formula unit of Sb4(SiO4)3 have
kotegsom [21]

Answer:

There are 19 atom sin total in antimony silicate, Sb_4(SiO_4)_3.

Explanation:

Number of antimony atoms = 4 × 1 = 4

Number of silicon atoms = 3 × 1 = 3

Number of oxygen atoms = 3 × 4 = 12

Number of atoms in antimony silicate:

= 4 + 3 + 12 = 19

There are 19 atom sin total in antimony silicate, Sb_4(SiO_4)_3.

natta225 [31]

Answer:

\boxed{\text{10 \%}}

Explanation:

The formula for efficiency is  

\begin{array}{rcl}\text{Efficiency} & = & \dfrac{\text{useful energy out}}{\text{energy in}} \times 100 \,\% \\\\\eta & = & \dfrac{w_{\text{out}}}{w_{\text{in}} } \times 100 \,\%\\\end{array}

Data:

Useful energy =  3 J

Energy input  = 30 J

Calculation:

\begin{array}{rcl}\eta & = & \dfrac{\text{3 J}}{\text{30 J}} \times 100 \,\%\\\\\eta & = & 10 \, \%\\\end{array}\\\text{ The efficiency is }\boxed{\textbf{10 \%}}
