The answer is A:algae growing on the glass. A Biotic Factor is any living thing in a ecosystem and a Abiotic is any non-living things like
B:gravel on the bottom of the aquarium
C:temperature of the water
<span>D:amount of oxygen in the water</span>
Answer:
5.12
Explanation:
5.22 x 10 - 3 = [?] x 10 - 2 (move - 2 to the other side with changed sign)
5.22 x 10 - 3 + 2 = [?] x 10 (divide both sides by 10)
[?] = (5.22 x 10 - 1) / 10
[?] = 5.12
Explanation:
The factor of matter are solubility, boiling point, melting point, temperature, density and reactivity
In case of endothermic reactions the system gains heat from surrounding and thus lead to decrease in temperature of surrounding making it cold as conpared to system and we can feel thus with a drop in temperature.
In case of exothermic reactions the system loses energy and thus itself becomes cold and increase the Temperature of surrounding.
Answer:
61 atm
Explanation:
You can calculate osmotic pressure using the following equation:
π = <em>i </em>MRT
In this equation,
-----> π = osmotic pressure (atm)
-----> <em>i</em> = van't Hoff's factor
-----> M = molarity (M)
-----> R = Ideal Gas Constant (0.08206 atm*L/mol*K)
-----> T = temperature (K)
The van't Hoff's factor is the amount of ions the substance dissociates into. Since sugar does not dissociate, this value is 1. After converting Celsius to Kelvin, you can plug the values into the equation and simplify.
<em>i</em> = 1 R = 0.08206 atm*L/mol*K
M = 2.5 M T = 25 °C + 273.15 = 298.15 K
π = <em>i </em>MRT
π = (1)(2.5 M)(0.08206 atm*L/mol*K)(298.15 K)
π = 61 atm
