Answer : The formula of carbonic acid is, $H_2CO_3$

Explanation :

Acid : It is a substance that has ability of donating proton or hydrogen ion, $H^+$ . That means, in acid hydrogen should be present in the compound.

The element carbonate is the non-metal polyatomic ion. The stable oxidation state of phosphate ion $(CO_3^{2-})$ is, (-2).

When the hydrogen combine with the carbonate ion, it forms hydrogen carbonate (carbonic acid). The formula of carbonic acid is, $H_2CO_3$ .

It is an ionic compound in which the a metal (hydrogen) react with the non-metal (carbonate ion) and combine with the an ionic bond by the criss-cross method.

Hence, the formula of carbonic acid is, $H_2CO_3$

Answer: New concentration of $HC_{6}H_{5}O^{2-}_{7}$ is 0.23 M.

Explanation:

The given data is as follows.

Moles of $HC_{6}H_{5}O^{2-}_{7}$ = 0.06 mol

Moles of $H_{2}C_{6}H_{5}O_{7}$ = 0.08 mol

Therefore, moles of $OH^{-}$ added are as follows.

Moles of $OH^{-}$ = $0.125 \times \frac{25}{1000}$

= 0.003125 mol

Now, new moles of $HC_{6}H_{5}O^{2-}_{7}$ = 0.06 + 0.003125

= 0.063125

Therefore, new concentration of $HC_{6}H_{5}O^{2-}_{7}$ will be calculated as follows.

Concentration = $\frac{0.063125}{0.275}$

= 0.23 M

Thus, we can conclude that new concentration of $HC_{6}H_{5}O^{2-}_{7}$ is 0.23 M.

When copper is bombarded with high-energy electrons, X rays are emitted. Calculate the energy (in joules) associated with the ph

Scrat [10]

Answer:

E = 12.92 × 10^(-16) J

Explanation:

Formula for energy is;

E = hc/λ

Where;

h is Planck's constant = 6.63 x 10^(-34) J.s

c is speed of light = 3 × 10^(8) m/s

λ is wavelength = 0.154 nm = 0.154 × 10^(-9) m

E = (6.63 x 10^(-34) × 3 × 10^(8))/(0.154 × 10^(-9))

E = 12.92 × 10^(-16) J
