The two most abundant elements in the universe are HYDROGEN AND HELIUM. Hydrogen is the most abundant element followed by helium.
Hydrogen is the lightest of all element and the first element to be formed, followed by helium which has just two atoms.
I think high pressure and low temperature
3-Methoxybenzaldehyde
4-Anisaldehyde
(I THINK THIS IS THE ANSWER IM NOT SURE)
PH scale is used to determine how acidic or basic a solution is.
we have been given the hydrogen ion concentration. Using this we can calculate pH,
pH = - log[H⁺]
pH = - log (1 x 10⁻¹ M)
pH = 1
using pH can calculate pOH
pH + pOH = 14
pOH = 14 - 1
pOH = 13
using pOH we can calculate the hydroxide ion concentration
pOH = - log [OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = 10⁻¹³ M
hydroxide ion concentration is 10⁻¹³ M
Answer:
c. ll and lll only
Explanation:
Algae are plant-like protists capable of photosynthesis in their cells (chloroplast). Like every other living organism that grows and reproduce, algae also requires nutrients for these processes to effectively occur.
Algae makes use of inorganic nutrients including sulphates, phosphates, nitrates etc which are found in fertilizers, detergents etc. In the presence of these compounds, algae tends to grow excessively to form a BLOOM. Hence, according to the question, nitrates and phosphates are the two inorganic nutrients algae makes use of.
