Answer: Option (C) is the correct answer.
Explanation:
A physical substance that occupies space and has mass is called matter. Every matter possesses some chemical and physical properties.
Chemical property is the property which occurs when there is change in chemical composition of matter. Whereas physical property is the property which occurs when there is change in the appearance of matter.
The chemical properties of matter does not depend on temperature, therefore, option (a) is not correct.
Every matter posses some mass therefore, option (b) is also not correct.
It is possible for matter to have similar chemical properties and different physical properties. For example, a very small piece of sodium and a very large piece of sodium will react chemically in the same manner whereas their physical property, in this case is the size, is different. Therefore, option (c) is correct.
Every matter has some chemical and physical properties. Thus, it is not possible that matter can have only physical property and no chemical property. Hence, option (d) is also not correct.
Thus, we can conclude that the statement it is possible for matter to have similar chemical properties and different physical properties is true about matter.
The answer is A because The fact of temperature on volume changes of substance.
Answer: A) ionic salt
Explanation: Chlorine has a high electronegativity of 3.0. Copper like most metals has a low electronegativity, So the bonding is ionic making the compound an ionic salt.
in 6.0 years it will be 450.00 heart beats
in 6.00 years it will be 450.000 heart beats
in 6.000 years it will be 450.0000 heart beats
Explanation:
Answer:
3.67
Explanation:
Step 1: Write the balanced equation
CO₂(g) + H₂(g) = CO(g) + H₂O(g)
Step 2: Calculate the value of the pressure equilibrium constant (Kp)
The concentration equilibrium constant (Kc) is 3.67.
We can calculate the value of the pressure equilibrium constant using the following expression.
where,
R: ideal gas constant
T: absolute temperature
Δn(g): moles of gaseous products - moles of gaseous reactants
Δn(g) = 2 mol - 2 mol = 0
Then,
Kp = Kc × (R × T)⁰ = Kc = 3.67
