M = 10.0 Kg
acceleration of gravity = 9.8 m/s²
F = M * a
F = 10.0 * 9.8
F = 98 newtons.
hope this helps!.
Answer;
-Not that reactive
The element found is not very reactive.
Explanation;
-If an element is found in nature in its pure elemental state then the the element found is not very reactive.
-There are many elements which are not much reactive. such as in metals- Ag, Au, Hg, Cu etc. and in Non metals- O2, N2, Inert gases etc.
-
For checking its chemical properties you will have to examine it with O2 or C-12.
I believe the answer is B
According to Charles's Law, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature assuming in a closed system. Mathematical equation is : V1/T1=V2/T2. 87 degrees Celsius equals 87+273.15=360.15 k, and standard temperature is 273.15 k. So, 180/360.15 = V2/273.15, V2=180*273.15/360.15 = 136.52 mL, which is the volume of gas at standard temperature.
