Answer:
3.) NH3
Brainliest if this helps please? (:
Since the direction of particle displacement in electromagnetic waves is also perpendicular to the direction of motion, generating the waveform of visible light and other forms of electromagnetic radiation, they are also transverse waves.
In a transverse wave, the displacement is perpendicular to the direction of motion (at an angle of 90 degrees Celsius). The direction of displacement (up and down) in the case of the ocean wave is perpendicular to the direction of wave motion (horizontally along the water), making it a transverse wave.
How far a particle has moved from its original starting position, or, in the case of an ocean wave, how high or low the water is, is measured by its displacement or amplitude.

Answer:
237.5 K.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm (P = 5.2 atm).
V is the volume of the gas in L (V = 15.0 L).
n is the no. of moles of the gas in mol (n = 4.0 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = ??? K).
∴ T = PV/nR = (5.2 atm)(15.0 L)/(4.0 mol)(0.0821 L.atm/mol.K) = 237.5 K.
Answer:
Sodium bicarbonate.
Explanation:
The gas produced during the mixing of bath bombs in water is Sodium bicarbonate. If the reaction is with citric acid then Sodium citrate can be produced. They are weak acid with bicarbonate base. These bath bombs can be a mixture of wet and dry substances and any shape can be mold.
Answer:
A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.
Explanation:
Salt bridge is a link between oxidation half and reduction half of a galvanic cell.
Functions of salt bridge are:
Maintaining electrical neutrality
Preventing cell from reaching equilibrium
For creating salt bridge, a U shaped glass tube is filled with an inert electrolyte. Electrolytes used in the salt bridge generally do not reacts with the cell chemicals.
Cations and anions of the electrolytes have same ionic conductivity and hence, migrate with the same speed.
Most commonly potassium chloride, sodium chloride and potassium nitrate are used as an electrolyte in salt bridge.
Electrolyte are generally mixed with agar agar to prevent mixing of chemicals in the two half cells.
