To what temperature should soup that contains cooked beef be reheated for hot-holding?
nirvana33 [79]

The temperature , <u>165 degree F</u> should soup that contains cooked beef be reheated for hot-holding.

Food should reach a temperature serving 135°F before it can be opened in the restaurant and warmed for hot holding. Within two hours, quickly reheat the food. If food is being served right away, it can be served anywhere at temperature as long that it as it was cooked and chilled appropriately.

TCS food must be totally chilled to 41°F or even below in 6 hours after being thoroughly cooled between 135°F to 70°F in 2 hours. Within four hours, TCS food made with ingredients at room temperature needs to be chilled to 41°F or lower.

Therefore, the temperature , <u>165 degree F</u> should soup that contains cooked beef be reheated for hot-holding.

Chemical equation below demonstrate that?<br> NEED HELP ASAP
zmey [24]

(a) Matter cannot be created and destroyed by a chemical reaction.

Explanation:

(a) Matter cannot be created and destroyed by a chemical reaction. (correct)

The number and type of atoms entering the chemical reaction are the same with the number and type of atoms leaving the chemical reaction.

(b) The reactants are the same substance as the products. (wrong)

You may see in the reaction that we have as reactants zinc and hydrochloric acid which react to form the products, zinc chloride and hydrogen.

(c) The number of molecules in the reactants are equal to the number of molecules in the products. (wrong)

As reactants we have 2 hydrochloric acid (HCl) molecules and as products 1  hydrogen (H₂) molecule. Zn is a metal and ZnCl is a salt.

(d) The atoms on the reactants side are changed into different atoms on the products side. (wrong)

The number and type of atoms entering the chemical reaction are the same with the number and type of atoms leaving the chemical reaction.

The enzyme, carbonic anhydrase, is a large zinc-containing protein with a molar mass of 3.00 x10^4 g/mol. Zn is 0.218% by mass o
tia_tia [17]

The mathematical expression for mass percent is given by:

Mass percent = \frac{mass of the compound}{molar mass of the compound}\times 100

Put the values,

0.218 percent of zinc = \frac{mass of zinc}{3.00 \times 10^{4} g/mol}\times 100

mass of zinc = 0.218 \times (3\times 100) g

= 0.654 \times 100 g or 65.4 g

Now, number of moles of zinc  =\frac{given mass in g}{molar mass of zinc}

= \frac{65.4 g}{65.38 g/mol}

= 1.00 mole

Number of atoms of zinc is calculated by the Avogadro number.

Now, according to mole concept

6.022\times 10^{23} molecules of enzyme consists of 6.022\times 10^{23} atoms of zinc

So, 1 molecule of enzyme contains  =\frac{6.022\times 10^{23}atoms of zinc}{6.022\times 10^{23} }

= 1 atom of zinc.

Hence, every carbonic anhydrase molecule consists of 1 atom of zinc.
