The crystal structure of an ionic compound depends on the sizes of cations and anions, as well as the ratio of cations to anions. The ratio of the cations and anions need to be even, otherwise, the crystal won't form.
So the answer would be D, both A and B.
The formula for time is Distance / Speed... so that would be taking note that 107 yard is 97.8 metre( 1 yard is 0.914 metre ) and then you finally find the answer by targeting 437. I'm not very good at explaining but try understanding the notes and you'll get it.
Answer:
The correct answer is - 800.
Explanation:
Given:
Total amount = ? or assume x
spend in buying birthday item = 3/4 of x
given to sister = 1/5 of x
remaining to mother = 40
solution:
the remaning amount = x- (3x/4+x/5) = 4=
=> x- 19x/20 = 40
=> x = 20*40
=> x = 800
thus, the correct answer is = 800
Answer: 3.61 L
Explanation:
To calculate the moles, we use the equation:
2 moles of produce = 3 moles of
0.1 moles of produce = moles of
According to the ideal gas equation:'
P = Pressure of the gas = 1 atm (NTP)
V= Volume of the gas = ?
T= Temperature of the gas = 20°C = (20+273) K = 293 K (NTP)
R= Value of gas constant in in kilopascals = 0.0821 Latm/K mol
Thus volume of oxygen at NTP obtained by decomposing 12.26 g of is 3.61 L
Answer:
During the processes of condensation, freezing, and deposition, water releases energy. The energy released allows the water molecules to change their bonding pattern and transform to a lower energy state. In the Earth system, this energy must be absorbed by the surrounding environment.
