Answer:
Option C. 760mmHg & 0°C
Explanation:
The standard pressure = 760mmHg = 1atm = 760torr = 101325N/m2
= 101325Pa
Standard temperature = 0°C =273K
From the above, the right combination is 760mmHg and 0°C
The statement "An atom with high ionization energy will form a positive ion more easily than an atom with low ionization energy" is false.
In this context , we will define ionization energy as the minimum energy required to remove a valence electron from a neutral atom in it's gaseous state. In a sense the ionization energy is a measure the amount of 'difficulty' of making something an ion. A high ionization energy means that it takes a lot of energy to remove a valence electron from that atom. A low ionization energy means that it is easy to remove a valence electron from the atom. It is known that group 1 elements generally have a low ionization energy. On the other hand, it is harder for noble gasses and group 7 atoms to loose electrons because they have higher ionization energy.
To form a positive ion, you have to remove an electron. When an electron is removed from an atom, there ion formed has more positive charges than negative charges in it, making it net positive. We have established that atoms with low ionization energy loose elections much more easily. We have also established that atoms with high ionization energy do not loose electrons easily. From this we can gather that the statement is false. An atom with high ionization energy will not form a positive ion more easily that an atom with low ionization energy.
Answer:
3132 is the answer
Explanation:
3BaCl2 + Al2S3 → 3BaS + 2AlCl3
Answer:
1L=1000mL
1000mL+300mL=1300mL
so the answer is d.1300mL
Explanation:
<u>Answer:</u> The density of NaCl solution is 3.930 g/mL
<u>Explanation:</u>
We are given:
Mass of cylinder,
= 21.577 g
Mass of NaCl and cylinder combined, M = 39.664 g
Mass of NaCl,
= 
To calculate density of a substance, we use the equation:

We are given:
Mass of NaCl = 18.087 g
Volume of NaCl solution = 4.602 mL
Putting values in above equation, we get:

Hence, the density of NaCl solution is 3.930 g/mL
