Answer:
When the two atoms are in contact, potassium readily transfers its outer electron to chlorine which readily accepts it, resulting in both atoms achieving a state of eight outermost electrons. With this electron transfer, the ionic bond in KCl is formed.
The relationship between a cathode and an anode involves electrons.
Because:- Any relationship between two compounds/atoms would be with electrons, as they determine the bonding etc.
Answer:
d. a brittle solid.
Explanation:
Hello!
In this case, since cesium fluoride is widely known as an ionic compound due to the large electronegativity difference, it is possible to discard a. due to its crystalline structure, b. because conducting solids are metals, c. because ionic compounds are not likely to be gases and e. because even when it is soluble in water, the problem is not referring to an aqueous solution; therefore, the answer is d. a brittle solid.
Best regards!
Answer:
Mass = 33.515 g
Explanation:
Given data:
Volume of ammonia = 45.0 L
Temperature = 57.0°C (57 +273 = 330 K)
Pressure = 900 mmHg
Mass of ammonia = ?
Solution:
Formula:
PV = nRT
We will use R = 62.364 (L * mmHg)/(mol * K) because pressure is given in mmHg.
900 mmHg × 45.0 L = n × 62.364L * mmHg/mol * K × 330 K
40500 mmHg.L = n × 20580.12L * mmHg/mol
n= 40500 mmHg.L/ 20580.12L * mmHg/mol
n = 1.9679 mol
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 1.9679 mol × 17.031 g/mol
Mass = 33.515 g
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.
Answer:
Heat is how hot something is and temperature is how hot OR cold something is.
