Answer:
B- Increase
Explanation:
In the event that the temperature is increased, the normal speed and dynamic energy of the gas atoms increment. In the event that the volume is held steady, the sped up the gas particles brings about more incessant and more powerful crashes with the dividers of the compartment, hence expanding the pressing factor
Answer:
Heterogeneous

Answer:- The speed of the satellite is 7.6 kilometer per second.
Solution:- It's a unit conversion problem that could be solved using dimensional analysis.
The given speed of the satellite is 17000 miles per hour and we are asked to convert it to kilometers per second.
given: 1 Kilometer = 0.62 mile
1 hour = 3600 second
Let's use this given info and plug in the values:
=
We round the answer to two significant figures, since the given number(17000) has only two significant figures.
So, answer is 7.6 kilometer per second.
Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density.
Answer:
Amount of Ca(NO3)2 produced = 14.02 g
Explanation:
The given reaction can be depicted as follows:
Ca(OH)2 + 2HNO3 → Ca(NO3)2 + 2H2O
Since it is given that HNO3 is in excess, the limiting reactant is Ca(OH)2
Now, Mass of Ca(OH)2 = 6.33 g
Molar mass of Ca(OH)2 = 74 g/mol
Based on the reaction stoichiometry:
1 mole of Ca(OH)2 forms 1 mole of Ca(NO3)2
Therefore, moles of Ca(NO3)2 produced from the moles of Ca(OH)2 reacted = 0.0855 moles
Molar mass of Ca(NO3)2 = 164 g/mol
