Answer:

1.35×10¹² μg

Explanation:

Mass (Kg) = 1350 Kg

Mass (μg) =?

Thus, we can obtain the mass of the adult rhino in micrograms (μg) by converting 1350 Kg to microgram (μg) as follow:

1 Kg = 1×10⁹ μg

Therefore,

1350 Kg = 1350 kg / 1 kg × 1×10⁹ μg

1350 Kg = 1.35×10¹² μg

Therefore, 1350 Kg is equivalent to 1.35×10¹² μg.

Rudik [331]

Explanation:

P1V1/T1 =P2V2/T2

V2 =P1V1T2/P2T1

0.59×0.05×273/1×308

V2 =0.03L

What is the specific heat capacity of propane in J/gC?
Anna007 [38]

Answer:

At ambient pressure and temperature the isobaric specific heat, CP, of gaseous propane is 1.68 kJ/kg K or 0.402 Btu/lb °F = cal/g K, while the isochoric specific heat, CV, is 1.48 kJ/kg K or 0.353 Btu/lb °F = cal/g K.

The ionization constant equation is:

K_{w}=1.0 × 10^{-14} at 25°C

the option is 1.

Explanation:

Sometimes in pure water one proton of the water molecule(hydrogen ion) will get attracted to the lone pairs present in another water molecule.This causes the hydrogen ion to leave the present water(leaving the OH^{-} behind) molecule ad gets attached to another water molecule leading  to the formation of the hydronium ion(H^{3} O{+},hydronium ion).

This process is called auto-ionization of water because the water molecule ionizes into H^{+} and OH^{-} ions.

<h2>H_{2}O<u>+</u>H_{2} O<u>→</u>H^{3} O{+}<u> + </u>OH^{-}</h2>

As such the equilibrium constant,which is measure of concentration of products to concentration of reactants,will be very slow.

∴the ionization constant of water at 25°C is 1.0 × 10^{-14}.

(i.e.)option<u> c</u> is correct answer [H^{+}]=[OH^{-}]
