Answer:
The answer to your question is letter d. Synthesis
Explanation:
a. In a decomposition reaction, one single reactant splits out and forms 2 or more products.
b. In a single replacement reaction, a single atom replaces the cation of a molecule.
c. In a combustion reaction, an organic molecule reacts with oxygen to form carbon dioxide and water.
d. In a synthesis reaction, two reactants or more reactants combine to form one single product.
e. In a double replacement reaction, two molecules interchange cations and anions.
Answer:
474.92 mL.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT</em>.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n is constant, and have two different values of (P, V and T):
<em>P₁V₁T₂ = P₂V₂T₁</em>
<em></em>
P₁ = 740 mmHg, V₁ = 450 mL, T₁ = 16°C + 273 = 286 K.
P₂ = 760 mmHg, V₂ = ??? mL, T₂ = 37°C + 273 K = 310 K.
<em>∴ V₂ = P₁V₁T₂/P₂T₁ </em>= (740 mmHg)(450 mL)(310 K)/(760 mmHg)(286 K) = <em>474.92 mL.</em>
Answer:
The temperature remains constant during change of state as during the process of changing state, only enough heat to change state is provided...These amounts can only change state and not temperature....This type of heat is known as <u>Latent heat</u>.
Latent is another word for hidden

Science is constantly changing as new things are always being discovered, therefore "it is consistent and does not need to change with new discoveries" is false.
