Answer: $0.711J/g^0C$

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

$Q=m\times c\times \Delta T$

Q = Heat absorbed= 192 Joules

m= mass of silicon (Si) = 45.0 g

c = specific heat capacity = ?

Change in temperature , $\Delta T=T_f-T_i=6^0C$

Putting in the values, we get:

$192=45.0\times c\times 6^0C$

$c=0.711J/g^0C$

The specific heat of silicon is $0.711J/g^0C$

The blue color in some fireworks occurs when copper(I) chloride is heated to approximately 1500 K and emits blue light of wavele

Art [367]

Given that,

Temperature, T = 1500 K

Wavelength, $\lambda=4.5\times 10^2\ nm$

To find,

The energy of one photon of this light.

Solution,

We know that, the energy of a photon is given by the formula as follows :

$E=\dfrac{hc}{\lambda}\\\\E=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{4.5\times 10^2\times 10^{-9}}\\\\=4.42\times 10^{-19}\ J$

So, the required energy is $4.42\times 10^{-19}\ J$ .

Use the internet or your textbook as a reference to compare and contrast the Arrhenius Theory of acids and bases vs. the Brønste

Answer and Explanation:

1. Arrhenius Theory which describes the concept protonic. The substance that gives H+ ions when diluted in water is called as an acid (e.g. HCl) and the substance that dissociates OH-ions whenever it is diluted in water is called as the base (e.g. NaOH)

on the other hand

Bronsted Lowery Theory describes the concept of a proton donor-acceptor. The proton-donating species is an acid and the proton-accepting species is known as a base.

2. The Chemical name and nature of acid is shown below:-

Nature Chemical Name

a. HCl Acidic Hydrochloric Acid

b. KOH Basic Potassium hydroxide

c. HNO Acidic Nitric Acid

d. Mg(OH)2 Basic Magnesium hydroxide

A solution of cough syrup contains 5.00% active ingredient by volume. If the total volume of the bottle is 11.0 mL , how many mi

Marta_Voda [28]

All you need to do is change 5% into a decimal which would be 5/100 = .05
then multiply the decimal by the total volume to get the amount of active ingredients in ml
.05 * 56ml = 2.8 ml of active ingredient.

Hope that helps!
