Answer:

5850\ \text{cal}

Explanation:

m = Mass of water = 4500 g

c = Specific heat of water = 1\ \text{cal/g}^{\circ}\text{C}

\Delta T = Change in temperature of water = 1.3^{\circ}\text{C}

Heat is given by

q=mc\Delta T\\\Rightarrow q=4500\times 1\times 1.3\\\Rightarrow q=5850\ \text{cal}

A slice of the bread contains 5850\ \text{cal}.

How many orbitals does the P sub shell contain
IgorLugansk [536]

Answer:

Contains 3 orbitals. Px, Py, Pz.

Explanation:

Orbitals are regions in space where there is a high probability of finding electron(s). Each p orbital can hold 2 electrons, which means 6 in total. Hence the p block of elements is six across. Orbitals are more specific in giving the exact location of electrons and scientists use these electronic configurations to identify and distinguish different elements.

HELP ASAP!!
Harman [31]
I would think it is a heterogeneous mixture since it can't be an element since there are more than one type of atom, it can't be a compound since the leaves are not bonded together, and it can not be a homogeneous mixture since the leaves don't all blended together (the pile is not uniform) and you can distinguish all the different parts of the mixture.  It can be considered a heterogeneous mixture since the leaves are mixed together (along with other things like dirt) in a non-uniform way so that you can point out the parts of the mixture and it does not look like one thing.

I hope this helps.  Let me know in the comments if anything is unclear.
