Answer:
It C
Explanation: Because consumers the producers and the producers get their energy from the Sun so that means that consumers are getting all their food from things that start that with the Sun.
Answer
is: concentration of hydrogen cations in lemon juice is 4.00 × 10−3 m.
pH
= 2.4.
pH
= -log[H₃O+].
[H₃O+] = 10∧(-pH).
[H₃O+] = 10∧(-2.4).
[H₃O+] = 0.004 mol/L.
pH value (potential of hydrogen - [H+]) is a logarithmic scale that
specify the acidity or basicity of an aqueous solution. When pH is greater than
seven, aqueous solution is basic, below seven is acidic and when pH is equal
seven, solution is neutral.
Answer:
if you search up the periodic table and go to any website it will let you press on the element and it will say if it is a gas,solid or liquid and it might say if it is man made!

Answer:
FALSE
nuetrons do indeed have no charge, however they are nearly 2000 more times massive than electrons.
A system that releases heat to the surroundings, an exothermic reaction, has a negative ΔH by convention, because the enthalpy of the products is lower than the enthalpy of the reactants of the system. The enthalpies of these reactions are less than zero, and are therefore exothermic reactions
