Answer:
the squid population could decrease, because the tuna population is increasing and they would eat more squid, so the dolphin population would also decrease because there would be less squid to eat, and because there are less squid the herring population would increase.
15:15 which cancels to 1:1 so for each mole of co2 u get a mole of carbon monoxide
brainliest and thanks plz:)))))))))))
Answer:
The correct answer is 25 mL graduated cylinder (it should be used in all the cases)
Explanation:
In order to measure 25.00 ml sample of a solution it should be used a 25 mL graduated cylinder, as it is previously and properly calibrated. The other laboratory glassware, beaker and erlenmeyer, have graduations which are approximate, so they are used when exact volumes are not needed.
ii) graduated cylinder has the least uncertainly. It is more accurate than a beaker or erlenmeyer (to within 1%)
iii) A 25 mL graduated cylinder should be used because it is the most accurate lab glassware (between those were mentioned: beaker, erlenmeyer).
The equation which we are required to complete can be completed as follows;
- AgNO3 + KCl ==> KNO3 + AgCl
<h3>Electrochemical series;</h3>
Most substitution reactions involve displacement of metals and non-metals.
The possibility of a substitution reaction to occur is sometimes dependent on the order of preference of the metals in the activity series.
On this note, In the reaction between AgNO3 and KCl, potassium, K displaces silver, Ag and the products of the reaction are; KNO3 and AgCl

Answer:
Explanation:
Hello,
In this case, considering the given chemical reaction, we can use the molar mass of octane (114.23 g/mol) and the 2:16 molar ratio with carbon dioxide to compute the emitted moles of CO2 to the atmosphere via the following stoichiometric procedure:
Which also corresponds to the following mass:
