You will use mass=mole x Molar mass
The molar mass of Na2CO3 is 106
So 0.45 x 106 = 47.7 grams
Normally the systemic arterial blood has a pO₂ of about 75-100 mmHg, a pCO₂ of about 35-45 mmHg, and a pH of 7,35-7,45.
Answer:
b. Lithium
Explanation:
<u>Lithium-ion batteries (LIB) is a rechargeable battery</u>. It was first proposed by M stanley Whittingham in 1970s. These kind of batteries are commonly used in electrical vehicles and portable electronics. It also have military , naval and aerospace applications.
<u>
In LIB, the lithium ions move from the negatively charged electrode to the positively charged electrode during the discharge process and move in the reverse direction when the during the charging process.</u> The battery uses an intercalated lithium compound is used to form anode and graphite is used to form cathode.
<u>Thus, Lithium is oxidized/reduced in a lithium ion battery.</u>
Answer:
Explanation:
Hello!
In this case, since this calorimetry problems can by analyzed by figuring out that the heat lost due to the combustion of C6H12O6 is gained by the water and the calorimeter which undergo the mentioned temperature rise, we can write:
Thus, by plugging in the given data, we obtain:
Next, we compute the moles of C6H12O6 by using its molar mass (180.18 g/mol) as shown below:
Thus, the value for q of the reaction turns out:
Best regards!
The answer is the plague, or the black death
