oic. thanks a lot.
y is directly proportional to x2
x is increased by 100%
find the percentage increase in y.
y= k x2
then y= k x2
y=k 4 x2
so 4 x2 is already increased by 100%?
then to find k which is
y=k 4 x2
k= y/ 4 x2
find the percentage increase in y,
so what i...
y is directly proportional to x2.
x is increased by 100%.
Find the percentage increase in y.
y= k (100 + x2)
then i went to find the k,
k= y/ (100 + x2)
so i put back the k which i found into y= k (100 + x2)
which is :
y= y/(100 + x2) (100 + x2)
does metals has the following?
Qns. high melting point, insoluble in water, conduct electricity in solid and liquid.
may i know what's the physical properties of covalent compound?
do they have low melting point?
does ionic compound has high melting point ?
can somebody correct...

ok. thanks. but to pick out 2 groups which contain 1 element, 1 compound and 1 mixture. so i should pick D and which one?
A.) gold, sodium chloride, steel. ( there's only one element. no mixture.)
B.) oxygen,iodine , air ( 2 elements. 1 mixture.)
C.) methane, iron(III)chloride, sea-water...
Only 3 statements are correct.
A.) Water is a compound and exist as molecules at rtp.
