Answer:
C. 2.
Explanation:
<em>CH₄ + 2O₂ → CO₂ + 2H₂O</em>
- It is balancing the equation that the number of the atoms is the same in both sides of reactants and products.
- That we have in both sides; 1.0 C atom, 4.0 H atoms, and 4.0 O atoms.
Answer:
Option A, The organism experiences a disruption in homeostasis.
Explanation:
When a pathogen enters the organism’s body, it disrupts its homeostasis. There are several receptors in the body that are responsible for maintaining the stability of the body through negative feedback loop.
A foreign element attaches to the surface of these receptors and hence disrupts their attachment with the probable substance necessary for the regulation of essential body function.
Thus, the temperature regulation get s impaired, hormonal imbalances occur, feeding system disturbs etc.
Hence, option A is correct
1. Water
2. Air and its molecule
3. Your body
and etc!
Hope this helps! Have a great day!

Answer:
The mass of nitrogen gas will be 31,3 g
Explanation:
We calculate the weight of 1 mol of N2 (nytrogen gas):
Weight 1 mol N2= 2 (weight N)= 2 x 14 g/mol = 28g/mol
The conditions STP are 1 atm of pressure and 273K of temperature. We use the formula:
PV=nRT
1 atmx 25,0L= n x0,082 l atm/K mol x 272 K
n= 1 atmx 25,0L/0,082 l atm/K mol x 272 K= 1, 12 mol
1 mol N2-----28 g
1,12mol N2---x= (1,12mol N2 x28g)/1 mol N2= 31, 3 g
