1. An endoskeleton is the internal support of the structure of an organism like bone, cartilage etc. An exoskeleton is a complex rigid outer covering of an organism which protects the muscles and soft tissues inside like a crab shell. Remember it like 'en' in endoskeleton is to enter so its inside, and 'ex' in exoskeleton is to exit so outside the animal.

2. Bone marrow is a semi-solid tissue which is inside the spongy part of bones. There are different colored bone marrow, and the different ones are just located in different types of bones. Bone marrow is important and helps because it is the primary location where the production of new blood cells occur.

In the following reaction, how many grams of NaBr will react with 311 grams of Pb(NO3)2?

Mashutka [201]

Molar mass :

NaBr = 103 g/mol

Pb(NO3)2 = 331.20 g/mol

Balanced chemical equation :

2 NaBr + 1 Pb(NO3)2 = 2 NaNO3 + 1 PbBr2

2*103 g NaBr ------------> 1 * 331.20 g Pb(NO3)2
g NaBr -------------------> 311 g Pb(NO3)2

331.20 g = 2*103*311

331.20 g = 64066

mass ( NaBr ) = 64066 / 331.20

mass ( naBr) = 193,43 g of NaBr

hope this helps!.

Bromine is is reddish-brown liquid that boils at 59 degrees. bromine is highly reactive with many metals, for example, it reacts

katrin2010 [14]

A physical property of an element is a property of an element that can observed or measured without changing the chemical nature of the element.

A chemical property of an element is a property of an element that can only be observed or measure when the chemical property of the element is altered or changed.

Based on this;
The boiling point of bromine is a physical property of bromine.
The high reactivity of bromine with many elements is a chemical property of bromine.

How to convert 5.2 km to mm

ZanzabumX [31]

5.2 km to mm.
1km = 1000m
= 5.2 * 1000m.
=5200 m. 1m = 1000mm

= 5200 * 1000mm
= 5200000 mm

since butane is not found on the periodic table,how could you find the molar mass of butane(mass of one mole of butane molecules

Wittaler [7]

We know, It's atomic formula = C4H10

Now, we know molar mass of C = 12 & H=1

so, it would be: 12*4+1*10 = 48+10 = 58

If we have 0.06 moles of HCI How many grams of magnesium metal is that?

vesna_86 [32]

Answer:

1.44 g

Explanation:

From the question given above, the following data were obtained:

Number of mole of HCl = 0.06 mole

Mass of Mg =?

From the question given above, we discovered the number of mole of HCl is equivalent to the number of mole of Mg. Thus,

Number of mole of Mg = number of mole of HCl

Number of mole of Mg = 0.06 mole

Finally, we shall determine the mass of Mg. This can be obtained as follow:

Number of mole of Mg = 0.06 mole

Molar mass of Mg = 24 g/mol

Mass of Mg =?

Mass = mole × molar mass

Mass of Mg = 0.06 × 24

Mass of Mg = 1.44 g

Therefore, the mass of magnesium is 1.44 g
