What are the sig figs in 10,024,500?

6 sf 

100
What is the formula/equation for density? 

d=m/v

mass/volume 

100

convert 20km to mm. 

2.0x10^7

100
Name where the non-metals and metals are on the periodic table 

non metal = right hand 

metal = left hand 

100

What exactly is a neutron? 

apart of an atom and it has a neutral charge. 

200
How many Sig Figs are in 0.02000?

4 sf 

200

If an object has the mass of 7.65g and the volume of 3.2mL what is the density? 

2.4g/mL 

200

convert 37 mL into km 

3.7x10^-8 

200

Name the alkali, alkaline earth, halogens, noble gases, and transition elements for each column. 

Any one can be named I will check after one is stated .

200

What's the difference between a neutron, electron and proton? 

Proton=positive charge in nucleus 

Electron = negative charge outside nucleus 

Neutron= neutral charge in nucleus

300

How many Sig Figs do you use when you multiply and add together? 

Multiply the least amount of SF then for addition make sure to go with the least amount past the decimal point. 

300

Does the units for density's volume matter? 

Yes, must always have volume in mL not L 

300

EXPLAIN how you would convert from km to mm

km-> m-> cm-> mm

300

what is the charge for a non-metal group? 

Negative (anion)

300

Do all elements on the periodic table have aspects of an atom? 

yes the periodic table is made up of elements that are made up of atoms. 

400

How many Sig Figs are present? 

600,89 x 7.90 

answer - 474703.1

Sig figs are 3 because you will put that answer into Scientific notion. 

400

if a graduated cylinder contains 18.4mL of water. After an object with a mass of 13.09g is placed in grad. cylinder, the volume reading increased to 30.8mL. What is the density?

1.06g/mL 


took 13.09/30.8-18.4

400

Steve races to the nearest taco stand at lunchtime and sees that his pedometer recorded his peak speed at 108.9 cm/s. What was Steve's peak speed in kilometers per hour?

3.920km/h


cm->m->km->s->min->h

400

What is the charge for a metal group? 

positive (cation)

400

Give the symbol for the following elements: 

Co

Br

H

Cl

Se

Co=cobalt 

Br=bromine

H=hydrogen

Cl=chlorine 

Se= selenium 

500

How many Sig Figs are present? 

7.89 x 9.0 + 8.678 =

There is 2 sig figs, because multiplication and addition rules.


500

What are the conversions associated with density? 

1g=1cm3

1g=mL 

500

The surface temperature on Mercury has been measured to be 381 K.What is this temperature in degrees Celsius?

381k-273.15

will get Celsius 

500

What is the difference between charges of a non-metal, metal, transitional metal and noble gasses? 

Non-metal is negative (anion) while metal is a positive (cation) and transitional metals are dependent on charge number but are cations. noble gases have no charge needed, there neutral. 
500
Are the following elements a metal or non-metal, and put the elements in their corresponding groups. 

He

Li

Cl


He=helium is a non-metal apart of the noble gases 

Li= Is a metal, a part of the alkali earth metals 

Cl= is a non-metal part of the halogens
