N(CuSO₄)=135/{63.5+32.1+4*16.0}=0.846 mol

n(CuSO₄*5H₂O)=135/{63.5+32.1+4*16.0+5*(2*1.0*+16.0)}=0.541 mol

n(H₃PO₄)=135/{3*1.0+31.0+4*16.0}=1.378 mol

n(BaCl₂)=135/{137.3+2*35.5}=0.648 mol

Why is electromagnetic radiation a transverse wave?
Yuki888 [10]

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.

A fixed number of moles of an ideal gas are kept in a container of volume V and an absolute temperature T. If T and V are both d
liubo4ka [24]

Answer:

If the temperature and volume ot a gas increases, the r.m.s. velocity of the molecules in the gas will be 2  times the original r.m.s. molecular velocity.

If T doubles while V is held constant, the new net internal energy of the gas will be 2 times the original internal energy of the gas.

Explanation:

Temperature and root mean square velocity are directly proportional to one anoth. If the temperature increases, root mean square velocity also increases and vice versa, while temperature is also directly proportional to the internal energy of the gas molecules, higher the temperature, higher will be the internal energy and lower the temperature so internal energy will be decreased.

Answer: 0.0450 moles of CaCl_2

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

\text{Number of moles of} CaCl_2=\frac{5.00g}{110.98g/mol}=0.0450moles

Thus there are 0.0450 moles of CaCl_2
