How much heat is required to raise the temperature of 65.8 grams of water from 31.5ºC to 46.9ºC?
vodomira [7]

Answer: 1,013.32 cal × 4.18 J/cal = 4,235.68 J

Explanation:

1) Data:

Water ⇒ C = 1 cal/g°C

m = 65.8 g

Ti = 31.5°C

Tf = 36.9°C

Heat, Q = ?

2) Formula:

Q = mCΔT

3) Calculations:

Q = 65.8g × 1 cal/g°C × (46.9°C - 31.5°C) = 1,013.2 cal

4) You can convert from calories to Joules using the conversion factor:

1 cal = 4.18 J

⇒ 1,013.32 cal × 4.18 J/cal = 4,235.68 J

If water were a linear (not bent) molecule like co2, electrostatic interactions between water molecules would be much weaker. wh
Ksenya-84 [330]

Answer;

The partial negative charge on oxygen would stick out less and be less able to participate in hydrogen bonding.

Explanation;

Water is a polar molecule because the electrons are not shared equally, they're closer to the oxygen atom than the hydrogen.

-Normally, the water molecule is a bent shape because of the pair of lone electrons - they repulse each other and exert a compression to the hydrogen atoms at a slight 104º angle. It is a bent molecular geometry that results from tetrahedral electron pair geometry.

-The 2 lone electron pairs exerts a little extra repulsion on the two bonding hydrogen atoms to create a slight compression to a 104 degrees bond angle. Therefore, the water molecule is bent molecular geometry because the lone electron pairs.

Thus, If water were a linear molecule like co2, electrostatic interactions between water molecules would be much weaker, then the partial negative charge on oxygen would stick out less and be less able to participate in hydrogen bonding.

An element from the periodic table is shown below. What can you determine about the number of protons, neutrons, and electrons o
Musya8 [376]

Answer:

They are all the same = 8

Explanation:

Since the symbol of that atom is not give, we can infer from the given number the nature and kind of element we are dealing with.

The number 15.999 rounded up to 16 is the atomic weight of the atom also called the mass number.

Although not peculiar enough, we are certain that this atom is Oxygen.

 On the periodic table, elements are arranged based on their atomic numbers.

    Atomic number of oxygen = 8 = number of protons

For every neutral atom on the periodic table, the number of protons and electrons are the same

Atomic number of oxygen = number of protons = number of electrons = 8

 Number of neutrons = Mass number - atomic number = 16 - 8 = 8
