Roman numerals are used in naming ionic compounds when the metal cation forms more than one ion. The metals that form more than one ion are the transition metals, although not all of them do this.
SnBr2 - Tin(II) Bromide
Answer:
I guess it all of these
as life cycle of an organism can be predicted and yeah it begins with birth hatching or germination for mammals, animals and plants respectively. then it's same for the organism of the same species .
Answer:
29260J
Explanation:
Given parameters:
Mass of water sample = 100g
Initial temperature = 30°C
Final temperature = 100°C
Unknown:
Energy required for the temperature change = ?
Solution:
The amount of heat required for this temperature change can be derived from the expression below;
H = m c (ΔT)
H is the amount of heat energy
m is the mass
c is the specific heat capacity of water = 4.18J/g°C
ΔT is the change in temperature
Now insert the parameters and solve;
H = 100 x 4.18 x (100 - 30)
H = 100 x 4.18 x 70 = 29260J
Answer:
If you spill an acid or base on your shoulder immediately wash well with water. Strong bases react with the oils in your shoulder to produce a soapy feeling layer. Rinse until well after that feeling is gone. Do not attempt to neutralize a spill on your skin.
The combined gas<span> law states that the </span>pressure of a gas<span> is inversely related to the</span>volume<span> and directly related to the </span>temperature<span>. If </span>temperature<span> is held constant, the equation is </span>reduced<span> to Boyle's law. Therefore, if you </span>decrease<span> the </span>pressure<span> of a fixed amount of </span>gas<span>, its </span>volume<span> will increase.</span>
