1.00*10^3
You’d need to lower the exponent because rounding to 3 sig figs changes the 9’s to - 1000. Keep the 0’s.
Answer:
69.8 kilo Pasacl is the pressure of the hydrogen gas.
Explanation:
Pressure at which hydrogen gas collected = p = 101.2 kilo Pascals
Vapor pressure water = 
= 31.4 kilo Pascals
The pressure of hydrogen gas = P
The pressure at which gas was collected was sum of vapor pressure of water and hydrogen gas.
69.8 kilo Pasacl is the pressure of the hydrogen gas.
A is true of UV rays.
B is true not of UV rays but rather of visible light.
C is true not of UV rays but rather of microwaves. (unless you actually toast your toast in a toaster like a normal person)
D is true not of UV rays but rather of radio waves.
Explanation:
An open system is a system that has external interactions. ... An open system is contrasted with the concept of an isolated system which exchanges neither energy, matter, nor information with its environment. An open system is also known as a flow system.
Answer:
Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together.
Explanation:
The interaction that occurs between atoms that have an electric charge is called electromagnetic force. When the charges are at rest, the interaction between them is called electrostatic force. This force depends on the distance "r" between the atoms.
Depending on the sign of the charges that interact, electrostatic force can be attractive or repulsive. The electrostatic interaction between charges of the same sign is repulsive (two negative charges or two positive charges), while the interaction between charges of the opposite sign (a negative charge and a positive charge) is attractive. In the case of neutral charges against negative or positive charges, no force is generated.
<u><em>Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together. </em></u>In this example you have a positively charged atom (Cs₊) and a negatively charged atom (Cl₋). As they are opposite charges they will attract.
