The process of water changing from a liquid to solid is called?

Answers

It must be freezing or condensation

Answer:

freezing

Explanation:

When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt. ... The reverse of the melting process is called freezing. Liquid water freezes and becomes solid ice when the molecules lose energy.

Explanation:

Which has the larger change hydration in each pair of a)Na+ Or cs+ b)Sr+2 or Rb+ c)Na+ or Cl- d) O-2 or F- e)OH- or SH-

Answers

Answer:

See explanation

Explanation:

The size of the hydration enthalpy of a system depends on the attraction between the ions and the water molecules. Stronger attractions exist between water and smaller ions. The smaller the ion, the higher the hydration enthalpy is.

In the first pair, Na+ is smaller than Cs+ hence Na+ has a larger change in hydration enthalpy.

In the second pair, Sr2+ is smaller than Rb+ hence Sr2+ has a larger change in hydration enthalpy.

In the third pair, Na+ is smaller than Cl- hence Na+ has a larger change in hydration energy.

F- is smaller than O2- hence F- has a larger change in hydration energy.

OH- is smaller than the SH- hence the OH- has a larger change in hydration energy.

Answers

Answer:

2.3 X 10^24 atoms CO2

Explanation:

Answer:

2.30 x10²⁴ molecules CO2

Explanation:

Convert mass of CO2 to moles

Convert moles of CO2 to molecules using Avogadro's number.

168.2 g CO2 x 1 mole CO2 / 44 g CO2 x 6.022 x10²³ molecules CO2 / 1 mole CO2

= 2.30 x10²⁴ molecules CO2

What is the mass of chlorine in 3.9 x 1019 molecules of Cl2?

Answers

Explanation:

A photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by

E=hf=hcλ(energy of a photon)E=hf=hcλ(energy of a photon),

where E is the energy of a single photon and c is the speed of light. When working with small systems, energy in eV is often useful. Note that Planck’s constant in these units is h = 4.14 × 10−15 eV · s.

Since many wavelengths are stated in nanometers (nm), it is also useful to know that hc = 1240 eV · nm.

These will make many calculations a little easier.

All EM radiation is composed of photons. Figure 1 shows various divisions of the EM spectrum plotted against wavelength, frequency, and photon energy. Previously in this book, photon characteristics were alluded to in the discussion of some of the characteristics of UV, x rays, and γ rays, the first of which start with frequencies just above violet in the visible spectrum. It was noted that these types of EM radiation have characteristics much different than visible light. We can now see that such properties arise because photon energy is larger at high frequencies.

High-speed winds transfer more energy to the ocean’s surface, creating bigger waves.



Question 10 options:
True
False

Answers

Answer:

I think that would be true. The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. Therefore, a wave's size depends on wind speed, wind duration, and the area over which the wind is blowing

Answer: True.

Explanation: Yes, waves get energy from the wind through friction, so you see those waves get bigger each time. The longer the winds blows, the more friction, and energy it's getting, meaning better, and deadly waves. The wind can sometimes cause tsunamis if the its blowing too hard.

Does anyone know how to do this?

Answers

Answer

find out the number of moles and use the molar ratio (numbers in front of formulas (in this case they are all 1) to determine how many moles of each product you are going to get theoretically

n=m/M is the equation to use to get moles here

30.8 gm/32.04 g/mol=0.9612 moles of the methanol and also of the formaldehyde so

0.9612 moles of the formaldehyde x molar mass (M) 30.73 g/mol= 29.54 gm which is the theoretical yield you already have the actual yield of 24.7 gm

then divide the actual by the theoretical to get the % yield which is 83.6%

A weight of 8.7 N is attached to a spring that has a spring constant of 190 N/m. How much will the spring stretch?

Answers

Given:
Fs=8.7N
K=190N/m
Unkown:
X=?
Equation:
Fs=Kx
8.7N=(190N/m)x
X=4.6*10power of-2m
The spring will stretch "4.6×10⁻2 m".

Given values are:

Force, Fs = 8.7 NSpring constant, k = 190 N/m

As we know the relation,

→ [tex]Fs = K\times x[/tex]

or,

→   [tex]x = \frac{Fs}{k}[/tex]

By putting the values, we get

        [tex]= \frac{8.7}{190}[/tex]

        [tex]= 4.6\times 10^{-2} \ m[/tex]

Thus the response above is right.
