Hey there!
C₅H₅ + Fe → Fe(C₅H₅)₂
Put a coefficient of 2 in front of C₅H₅ on the left side because there is a subscript of 2 after C₅H₅ in parenthesis on the right.
2C₅H₅ + Fe → Fe(C₅H₅)₂
Fe (iron) is already balanced since there is one on each side, so we don't need to change anything for that.
This is a synthesis reaction because two reactants, C₅H₅ and Fe, are yielding a single product, Fe(C₅H₅)₂.
Hope this helps!
The question is incomplete as it does not have the options which are:
(1) receiving antibiotic injections after surgery
(2) choosing a well-balanced diet and following it throughout life
(3) being vaccinated against chicken pox
(4) receiving hormones contained in mothers milk while nursing
Answer:
Being vaccinated against chicken pox
Explanation:
Vaccination is the procedure of giving the disease-causing germs which could be virus and bacteria in their dead or weakened state, some toxin, some proteins or some other molecules called a vaccine.
The benefit of providing vaccination is that the provided pathogen acts as an antigen and triggers the proactive immune response against the pathogen which helps in eradicating the main pathogen that has invaded the body. The vaccination is used to treat the disease like chickenpox, measles, tetanus and many others.
Thus, the selected option is correct.
The answer is long wave length because long wave lengths contians less energy, and would not harm living things such as plants and animals. the more engey a wave length has, the less harmful it is.
short wave length: lots of energy, extremely hot. (examples: gamma rays, and UV (ultraviolet) rays.
long wave lengths: not much energy, safe for humans and other life on Earth.
hopefully this helps.
Answer:
P2 = 1250mmHg
Explanation:
V1 = 5.0L
P1 = 750mmHg
V2 = 3.0L
P2 = ?
According to Boyle's law, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.
P = k/V k = P*V
P1*V1 = P2*V2 = P3*V3 =........=Pn*Vn
P1 *V1 = P2 * V2
Solve for P2
P2 = (P1 * V1) / V2
P2 = (750 * 5.0) / 3.0
P2 = 3750 / 3
P2 = 1250mmHg
The final pressure of the gas is 1250mmHg
The atomic number of an element tells you the number of protons within said element.
